- Shael in the bow, 15 IAS jewels in the helm and the armor to get 120IAS and 9/2 Strafe.
- Shael in the bow to get 90IAS and 9/3 Strafe.
- Nef in bow to get knockback.
- Amn in bow to get life leech.
- PTopaz in helm and armor to up MF.

Mav's does work pretty well for a Strafer setup. I would think, though, that AR is not exactly a problem as the Diadem grants a 50% AR bonus. With 1 point in Penetrate + dual Ravens, I have 9K AR on my Mav Frostmaiden for Strafe before buffing from Demon Limb, and after, I have 15K AR. (1 point in both Strafe and Penetrate.) I know that I could boost that quite a bit more if I swapped my +50 mana grand charms for +100 AR gcs I have on other chars. I think 5-10 points in Penetrate should be all right for a Mav's Strafer in PvM, so it wouldn't be necessary to max it, unless you plan on PvP. You'll have insane AR anyway after buffing.

I would recommend more in Critical Strike or hybrid skills like CA/FA (which this set is just awesome for) or CS + LF (for bosses). Also, I would recommend less Vita and more Dex. Maybe 50-100 points in Vita so you have 600-700 life, then rest into Dexterity after your Strength needs have been met. (Aiming for like 250-350 Dex eventually.) You are a Strafer, after all, and extra Dex helps to generate more damage. Also, your minions should be taking most of the pounding. The set's high resist bonuses and addition to your D/A/E skills should allow you to avoid most danger.

I went glass cannon on my girl (almost all Dex), and she still is extremely safe in Hell with 450 life. Better than my Witchyzon, I dare say. Atma's is the best amulet for the Strafer build. You can get some really nice damage then. I use Mara's on my girl, but that's because she's a Frostmaiden instead of a dedicated Strafer.

This build is easy to use, safe, able to kill everything. And, yes, it even has 100 MF.
The only attack skill is Strafe, so there is no need to check who's the enemy, just get behind mercenary, valkyrie and decoy, push the right button and watch them die.
The backup skills like FA/CA and CS/LF just make it more complicated and less safe.

what do you use for leeching???
i was thinking bul kathos and raven frost (might just have to get 2 bul kathos for enough leech), and highlord's wrath or eye of etlich (eh, it's got +1 and life leech). there are no boots with leech, so i was thinking gore riders or war travs. either way, how do you solve the problem of leech and what kind of merc do you think is best?

Nice build. 2 things I would probably change are the slvl1 Critical Strike and low Dex. I would at least aim for ~60% or slvl12 in there. Slvl13 actually for 61% but I dislike odd numbers. I would rather have a less godly valk which I think still is immortal by the way and have more damage with high slvl CS. For Dex I require at least 300 for my bowazons and the rest goes to Vit.

I got Mavs set on my strafezon which sets up 70 ias from bow and helm.
I have an open socket on helm, armor and bow and been reading about these strafe IAS bugs, but still not really geting a hang of it...

Would it make any difference on the strafe speed if I socket a 15ias jewel on it or would it be nicer to socket it with an EnhanceDamage jewel instead?

it will put you on a 9/3 breakpoint - you were on 10/3. That doesn't seem impressive to me. On the other hand, your normal breakpoint - and yes, multi/fa is usefull aswell - is only 10 fpa - were 90 ias will put you at 9 fpa. Going for 9fpa seems usefull if you ask me.
